Comment 4 for bug 1680731

ZOMGBBQ - you know what it *might* be - if a client *sends* 'Connection: keep-alive' (which is redundant in http 1.1 but not invalid) the most insane thing comes back:

ubuntu@saio:~$ curl -H 'x-auth-token: AUTH_tkbda4caa25b4f4f60a50ec26207487741' http://saio:8080/v1/AUTH_test/ec-test/deleteme -H 'connection: keep-alive' -v

That is interesting and could very well invalid, and almost definitely could cause problem for otherwise reasonably behaved clients...

without the raw dump curl seems to sort out the correct answer:

ubuntu@saio:~$ curl -H 'x-auth-token: AUTH_tkbda4caa25b4f4f60a50ec26207487741' http://saio:8080/v1/AUTH_test/ec-test/deleteme -H 'connection: keep-alive' -I

Connection: keep-alive

swiftclient has a slightly different opinion
